为挖掘产量性状好、养分利用效率高、生态适应性广的优良花生品种,在冀中低平原和山前平原两个生态区分别测定了19个花生品种的16个生物量和养分累积量指标,通过主成分分析对不同品种在不同生态区的表现进行了综合评价.按照主成分对应特征值大于1的原则提取主成分,将16个主要性状指标综合成4个主成分,可代表花生生物量和养分利用性状85%左右的原始信息量.结果表明:不同花生品种在不同生态区域的产量和养分利用效率存在较大差异.根据生态适应性将19个花生品种分为2类,生态适应性广的品种又分为产量水平和养分利用效率高、中、低3类,其中豫花9719、冀花0212-4、潍花10号、豫花15号、濮花28号和冀花10号为生态适应性广、养分利用效率高、产量水平也较高的品种.
In order to excavate fine peanut varieties with good yield traits, high nutrient use efficiency and wide ecological adaptability, 16 biomass and nutrient accumulation indexes of 19 peanut cultivars were determined in two lowland and piedmont plains of Jizhong, , Through the principal component analysis of different species in different ecological performance of a comprehensive evaluation.According to the principle of the corresponding eigenvalue greater than 1 principle to extract the principal components of the 16 major traits integrated into four principal components can be represented on the peanut Yield and nutrient use efficiency of different peanut varieties in different ecological regions are quite different.According to the ecological adaptability, 19 peanut varieties are divided into 2 categories, and the ecological adaptation Wide varieties are divided into the level of production and nutrient use efficiency, high, low 3 categories, including Yuhua 9719, Jihua 0212-4, Weihua 10, Yuhua 15, Puhua 28 and Jihua 10 No. Wide ecological adaptability, nutrient utilization efficiency, high yield varieties.
